CAR-TRUCK.

Specification of Letters Patent.

Patented March 17, 1908.

Application filed. July 12, 1907. Serial No. 888,452.

To all whom it may concern:

.Be it known that I, THEODORE H. CURTIS, a citizen of the United States, and a resident of the city of Louisville, in the county of J efferson, and State of Kentucky, have invented certain new and useful. Improvements in Car-Trucks, of which the following is a full, clear, and exact description. My invention relates to car-trucks, and esecially to cast integral or built up sideames and the truck-bolster, and has for its principal objects thefollowing: The intergal side-frame with provisions for inserting the integral truckbolster and "the u standing thrust-1n cooperating with the tiirust-luguides, t e rigidly securing of the sideames together by the spring-beam which holds the side-frames in proper alinement, the removable oil-cellars to permit the removal of the car-wheels and axles from the side-frames without removing any part except the oil-cellars, the construction of a cartruck e'mbodyi thev inte ral side-frames and integral truc -bolster, t ereby eliminatoil-cellars, and also the providing of means for keeping the side-frames substantially in alinement and rigidly held together and still permitting of quick removal of the carwheels and axles or the truck bolster, which is accomplished by means hereinafter described and particularly pointed out in the claims. a

In the accompanying drawings, forming a part of this specification and wherein like symbols refer to like arts wherever they occur, Figure I is a full truck showing a small section at the corner of the truck bolster. Fig; 11 is a sectional view through the center of the car-truck, and Fig. III is a full end view of the car-truck. Fig. IV is a sectional view through the center of the truck-bolster and side-frame showing spring-beam'with the bolster springs and spring seat removed. Fi V is a sectional view through the center 0 the truck-bolster and spring-beam showing the respective clearance of'same.

The side-frame, 1, with the bolster-o ening, 11, therein, is made with the journaloxsaddles, 2, cast integral with the side-frame and the oil-cellars, 3, attached by the bolts, 4. If desired the oil-cellars can be attached to the side-frames when same extend over i the journal-box-saddles, 2. The journalbox-saddles, 2, and the oil-cellars, 3, are prefing the use of bolts except those securingthe side view of the car erabl I formedwith the well known Master Car receive the Master Car Builders contained parts, such as the journal bearing and the ournal-beari -key and axle dust guard, also the journa -box-lid.' The side-frames, 1, are held rigidly together by the spring-beam, 6, with rivets, 17, securing the s ring-beam to the extendedframes.

The truckebolster, 10, is made with springseats, 19, and upstandingthrust-lugs, 9, one near each end of the truck-bolster, and each thrust-lug is located to cooperate with two thrust-leg-guides, 12, 12, over the bolsteropenin 's m each side-frame. The two thrusteg-guides form between them a air of guides in each side-frame, that each side-' frame 'ma revent the endwise shifting of the truckol ster in either direction.

The width and height of the truck-bolster is less than the width and height of the bolster-openings, 11, in the side-frames, thereby permitting} the inserting of the truck-bolster in the be ster-openings, 11, andwhen inserted the truck-bolster is raised and the thrust lugs, 9, cooperate with the thrust-lugguides, 12, of the side-frames, 1. When'the olster-springs, 8, are applied under the spring-seats, 19, and when restin lower spring-seats, 7, the truck-b0 ster will be held in position and secured to resist endwise shifting by the thrust in s, 9, cooperat-' in with the thrust-lug-guirfias, 12, of the si e-frames, 1, and to resist sidewise shifting by the sides of the truck-bolster cooperating flanges, 16, o the sideon the uilders standard dimensions, and to with the vertical sides of the bolster 0 enings, 11, in the side-frames, The truck- 01- ster can then be removed at any time by raising same until the frame seats, 18, strike the bottom of the thrust-1n -guides, 12, of

the side frames, which will re 'eve all weight" on the bo1stersprings and permit their removal. When the bolster-springs are removed the truck bolster can be lowered until the thrust lugs, 9, disengage the thrust-lu uides, 12, of the side-frames and the true holster can be taken out of the side-frames endwise;

The lower spring-seats, 7, rest u on the extended flanges, 16, of the sideames and also upon' the spring-beam, 6. The carwheels, 13, are mounted on axles, 14. The journals, 15, revolve under the journal-boxsaddles, 2.

Obviously the construction. of this car- .;';al-box saddles are ermanently secured to "the side-trame, or t e truck admits of modifications within the cable to a built-up side-frame when t c 10111- truck-bolster can be made of the built-up design and be substituted for the truck-bolster cast integral.

' What I claim as my invention, and desire to secure by Letters Patent, is:

4 1. In a railway car-truck, thecombination of the side-frames having bolster-o enings to receive the ends of the truck-b0 ster, that portion of each side-frame over each bolsteropening being provided with a pair of thrustlug-guides, and a truck-bolster having upstanding th'rustlugs to cooperate with said pair of thrust-lug-guides in each side frame, the pair of thrust-lug-guides in each sideframe and said cooperating thrust-lugs constituting the means for preventing endwise shifting of the truck-bolster, substantially as described.

2. In a railway car-truck, the combination of side-frames having bolster-openings to rereceive the ends of the truck bolster, that portion of said side-frames over said bolsteropenings being" provided with thrust-luguides and a truck-bolster having upstandmg thrust-lugls to cooperate with said thrustlug-guides, t e latter and said thrust-lugs constituting the means for preventing en Wise shifting of the nal-box saddles at ends of each side-frame and removable oil cellars attached to the journal-box saddles, substantially as described.

3. In a railway car-truck, the combination of side-frames having bolster-openings to receive the ends of the truckbolster,- that portion of said side-frames over said bolsteropenings being provided with thrust-lugguides, and a truck-bolster having upstanding thrust-lugs to cooperate with said thrustlug-guides, the latter and said thrust-lugs constituting the means for preventing endwise shifting of the truck-bolster and journalbox-saddles at ends of each side-frame and I truck-bolster and j ourcast integral with the side-frame and removable oil-cellars attached to the journal-boxsaddles, substantially as described.

4. In a railway car-truck, the combination of side-frames having bolster-openin s to receive the ends of the'truck-bolster, t at portion of said side-frames over said bolsteropenings being provided with thrust-lugguides and a truck-bolster having upstanding thrust-lugs to cooperate with said t rust-lugguides, the latter and'sai-d thrust-lugs constituting the means for preventing endwise shifting of the truck-bolster and j0prnal-boX-- saddles at ends of each side-frame and permanently secured to the side frames and removable oil-cellars attached to the journaL.

box-saddles, substantially as described.

5. In a railway car-truck, the combination of side-frames having bolster-openings to receive the ends of truck-bolsters, that portion of said side-frames over said bolsteropenings being provided with thrust-lug guides, and a truck-bolster having upstanding thrust-lu s to cooperate with said thrustlug-guides, t e latter and saidthrust-lugs constituting the means for preventing endwise shifting of the truck-bolster and journalbox-saddles atends of each side-frame and removable oil-cellars attached to the sideframes, substantially as described l 6. In a railway car-truck, the combination of side-frames having bolster-openings to receive the ends of the truck-bolster, that portion of said side-frames over said ,bolster openings being provided with thrust-lugand a truck-bolster having upstanduides, I ing thrust-l s to cooperate with said thrustlug-guides, t e latter and said thrust=lugs constituting the means for preventing endwise shifting of the truck-bolster and journalbox-saddles at ends of each side-frame and removable oil-cellars and a spring-beam conmeeting said side-frames and attached thereto, substantially as described.
